I had 2" crack on top of the radiator. I tried JB Weld and other similar putty but they did not work on plastic. I bought Permatex PermaPoxy™ 5 Minute Plastic Weld from Advanced Auto Parts for $7. It took 10 minutes to finish the job and it worked.

To fix a crack in a plastic bathtub, you can use a bathtub repair kit that includes a filler compound. Clean the crack, apply the filler, and let it dry according to the instructions. Sand the area smooth and apply a waterproof sealant for a lasting repair.
A plastic radiator will crack under extreme over heat conditions for example a defective thermostat or bad cylinder head gasket will cause a cooling system to over pressurise and rupture.
When a radiator has a crack, it can lead to coolant leakage. This can cause the engine to overheat, leading to potential damage if not addressed promptly. It is important to repair or replace the radiator to prevent further issues with the vehicle's cooling system.
you don't repair a radiator overflow jug as they are usually plastic. Buy a new or used one from a sslvage yard.
